 NFCore is a community effort to collect a curated set of analysis pipelines built using NextFlow. NextFlow is a leading workflow manager able to handle the complexity and parallelization of modern bioinformatics analyses. NextFlow pipelines work on almost any computational infrastructure and have support for common software packaging solutions. The NFCore community develops best practice workflows for a range of data types that all adhere to a strict set of guidelines. Pipelines are highly reproducible, open source and work in a consistent manner, so if you can run one, then you can run them all. For developers, helper tools get you up and running with a starter template. Automated testing ensures that your pipeline meets all of the NFCore guidelines. The NFCore user community is centered around GitHub and Slack where you can get help and advice. To find out more and to join NFCore, please visit our website.
